索洛模型指出了一个国家经济的长期增长率是由资本和劳动所共同决定的。()
此题为判断题(对,错)。
此题为判断题(对,错)。
B、该经济体的人均资本将会永远保持增长
C、该经济体的资本与劳动比将会下降
D、该经济体将保持高增长率,直到达到一个更高的资本劳动比
a.把人均产出(y=Y/L)表示为人均资本(k=K/L)和自然失业率的函数。描述该经济的稳定状态。
b.假定政府政策的某些变化降低了自然失业率。描述这一变化随时间的推进如何影响产出。对产出的稳定状态的影响大于还是小于立即的影响?请解释。
Consider how unemployment would affect the Solow growth model. Suppose that output is produced according to the production function Y=Kα[(1-u*)L]1-α,where K is capital, L is the labor force, and u*is the natural rate of unemployment. The national saving rate is s, the labor force grows at rate n, and capital depreciates at rate δ.
a.Express output per worker (y=Y/L) as a function of capital per worker (k=K/L) and the natural rate of unemployment. Describe the steady state of this economy.
b.Suppose that some change in government policy reduces the natural rate of unemployment. Describe how this change affects output both immediately and over time. Is the steady-state effect on output larger or smaller than the immediate effect? Explain.
